I use a Northern TooL grinder. Beast of a machine for $99. I use a food saver. Had a cheaper Black and Decker, but when using it traces of blood would sucked get into the sealing area and the sealer wouldn't get hot enought to seal the bag. I would highly suggest a food saver. I also have several fillet knives, couple big bowls and pans, and 2 cutting boards.
Cold meat is easier to grind and was nessecary with my previous grinder but the northern never slows down. However, if you'll put the meat uncovered in the frig so it drains the blood out for about 2 days, remove it, the outer layer will be dry. Just skin it off, it removes the hair and dirt and your mest will be delicious because the blood will be out of it. Just make sure it doesn't lay in the blood. You can use cookie racks or place a towel under the rack below the meat.
Cube it, get the silver skin and fat off, and you got primo grub regardless of steaks, roasts, or burger. God Bless
